is filled with the material to be spread and the rotation of the feeding drum or'roller causes the troughs of the successive corrugations to receive small portions of the material and carry it past the edge of the gate 16 whence it will drop to the ground. The rotation of the agitators serves to prevent clogging of the material in the lower portion of v the hopper so that it will flow evenly and smoothly to the feeding roller and will therefore, be discharged in a steady con tinuous stream. The material will be deposited in a thin line along the field and may be subsequently spread by hauling a drag over the same or by manual operation or by other preferred means. The spreader is exceedingly simple in its construction and compact in the arrangement of its parts so that it will operate easily and will not be apt to get out of order.

Having thus described the invention, I claim:

A spreader comprising a hopper having a tapered lower portion terminating in an outlet slot extending longitudinally of the hopper, vertical hangers carried by said hopper at the ends thereof and disposed in spaced relation to the tapered lower portion thereof, a feeding roller extending longitudinally of said hopper in operative relation to said outlet slot and having a shaft projecting from its ends and rotatably connected with said hangers, agitators in said hopper having shafts rotatably supported in the tapered lower portion thereof with their ends projecting at one end of the hopper, means carried by the shafts of said roller and agitator between one hanger and the adjacent tapered end portion of said hopper for transmitting rotary motion from the roller shaft to the agitator shafts, a drive shaft rotatably connected with the last-mentioned hanger, and means for transmitting rotary motion from said drive shaft to said roller shaft. In testimony whereof I aflix my signature.
